Symantec Messaging Gateway retains data about the messages that administrators and end users submit for ruleset creation along with the accompanying rules. You may want to delete customer-specific spam data to remove previous rules and start with entirely new rules. If you no longer want to leverage customer-specific rules in your environment, you can permanently delete all of customer-specific spam data. Afterwards, you should also disable the feature.
When you delete customer-specific spam data, you delete all of the following:
All of the data that was submitted for the creation of rules
All of the rules that Symantec created based on that data
Data that is used in spam submission reports
The submitter ID
All of the email addresses in the Submitter Email Address list
Once you delete the customer-specific spam data, it cannot be retrieved.
In addition, the aggressiveness option returns to the default setting, and Symantec Messaging Gateway no longer takes the actions that you specify for the spam policy condition If a message is customer-specific spam.
You must have Full Administration rights, Manage Spam Submission, or Manage Settings modify rights to perform this task.
To delete customer-specific spam data
In the Control Center, click Spam > Settings > Submission Settings.
On the Configuration tab under Customer-specific Spam Data Retention, click Delete All Customer-Specific Spam Data.
In the confirmation dialog box, read the warning and then click Delete All Customer-Specific Spam Data.
